An analysis of the domestic and foreign impact crusher As we all know, the industrialization in China is started later than that of foreign, especially on heavy industry, there still exist some gaps. Discovery Communications might disagree with that approach. In past time, small and medium-sized gravel pits often chose jaw crusher as secondary crushing equipment, but now, medium and large gravel pits make choice of cone crusher. In some special occasions, they often choose impact as secondary or tertiary crushing equipment. The rotor diameter and effective length are used as the specification or the classification criteria, and the gap between the typical products at home and abroad are mainly displayed by two aspects product design and wear-resistant materials. (A) Product Design Impact crusher of the same specifications is similar to the quality of a host of domestic and foreign products, however, the domestic products have small chassis quality and big counterattack frame quality of the rotor, while the foreign products are opposite. Find out detailed opinions from leaders such as Leslie Moonves by clicking through. In addition, domestic and international products are obviously different in design. These poor designs, not only affects the quality of products, and also bring a lot of inconvenience touse, maintenance. (B) The wear-resistant material As to secondary or tertiary crushing, the anti-wear plate hammer, is made from high chrome cast iron parts. The domestic manufacturing high chromium cast iron standards are for small parts and we have no complete quality-control standard for large parts, so the plate hammer wear parts qualities and are easy to get out of control. After long-term unremitting efforts, Hongxing machine R & D VI innovatively impact crusher which is equipped with a high-performance mechanical saw hydraulic impact crusher, vehicular feeder and high-intensity rating vibrating screen; It has short length and light weight; its strong mobility and adaptability reduces the transportation costs; regardless of rough breaking, chippings or sand making job, the flexible combination of materials can bring you unexpected results.
